Utility Model Content

[0005] The purpose of the utility model is to provide an automatic feeding device for a foam molding machine to solve the problem that it is difficult to achieve the purpose of uniform feeding during the feeding process of the device, and at the same time the device does not stir the raw materials sufficiently, which easily causes the raw materials to condense, and the dust generated during the stirring process also easily causes pollution.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an automatic feeding device for a foam molding machine, comprising a silo, a driving motor is fixed on the top surface of the silo, a rotating shaft is provided at the output end of the driving motor, a plurality of stirring blades are provided on the peripheral wall surface of the rotating shaft, and the maximum distance between each two corresponding stirring blades is similar to the diameter inside the silo, a connecting rod is fixed on the bottom surface of the rotating shaft, a spiral roller is fixed on the bottom surface of the connecting rod, a buffer tube is fixed on the bottom surface of the silo, the vertical cross-section of the buffer tube is trapezoidal, and the diameter of its bottom gradually increases from bottom to top, the bottom surface of the buffer tube is connected to a feed pipe, and the maximum diameter of the spiral roller is similar to the diameter inside the feed pipe and the height is the same.

[0007] Preferably, two slide grooves are provided on the inner wall surface of the silo, a driving slide is provided inside the slide groove, a snap-in hole is provided on the top surface of the driving slide, and the diameter of the two snap-in holes after contact is the same as the diameter of the connecting rod.

[0009] Preferably, a feed port is provided on the top surface of the silo, a threaded groove is provided on the inner wall of the feed port, a twist cover is provided inside the feed port, and the twist cover is threadedly connected to the threaded groove on the inner wall of the feed port.

[0010] Preferably, a fixing ring is fixed to the peripheral wall surface of the silo, an electric push rod is fixed to the bottom surface of the fixing ring, a base is fixed to the bottom surface of the electric push rod, a control panel is provided on the top surface of the base, the driving motor, the driving slide, the vacuum cleaner, the electric push rod and the control panel are electrically connected, and the base is fixed to the filter box.

[0011] Preferably, a placement groove is provided on the top surface of the base, and the placement groove is located directly above the material delivery pipe.

[0012] Compared with the prior art, the automatic feeding device for a foam molding machine using the above technical solution has the following beneficial effects:

[0013] 1. During use, the staff first starts the two driving slides through the control panel to make the two driving slides contact each other. Since the diameter of the two clamping holes after contact is the same as the diameter of the connecting rod, the bottom surface of the silo is in a closed state. Then the staff pours the raw materials into the silo through the feed port. At this time, the staff can start the driving motor through the control panel. The rotation of the driving motor drives the rotating shaft to start rotating. During the rotation of the rotating shaft, several stirring blades on the rotating shaft begin to stir the raw materials in the silo. After a period of stirring, the staff can start the two driving slides through the control panel to separate the two driving slides. At this time, the stirred raw materials will fall into the buffer tube under the action of gravity. Since the buffer tube is connected to the feed pipe, the raw materials will enter the feed pipe. Since the vertical cross-section of the buffer tube is trapezoidal, the diameter of its bottom gradually increases from bottom to top. In the process of the raw materials entering the feed pipe, the flow will be limited, thereby preventing too much raw material from falling at one time and forming a blockage. As the raw materials enter the feed pipe, the spiral roller, connected to the rotating shaft via a connecting rod, rotates with the shaft. Since the maximum diameter of the spiral roller is similar to the internal diameter of the feed pipe and the same height, the raw materials fall evenly from the bottom of the feed pipe into the mold under the action of the spiral roller. The connected spiral roller, rotating shaft, and slidable drive slide ensure that the device not only fully stirs the raw materials but also evenly discharges them, preventing them from agglomerating and improving the stability of the device.

[0014] 2. During use, after the staff pours the raw materials into the silo through the feed port, they can thread the twist cover into the threaded groove on the inner wall of the feed port to seal the top surface of the silo. During the process of stirring and feeding the raw materials, the staff can start the vacuum cleaner through the control panel. Since the suction end of the vacuum cleaner is connected to the inside of the silo, the dust generated during the stirring and feeding process will be absorbed by the vacuum cleaner and enter the filter box through the duct. Since the filter box is equipped with a filter plate inside, the air will be filtered by the filter plate, thereby filtering the dust in the air in the filter plate, preventing dust from flowing out of the feed pipe to a certain extent, thereby avoiding physical illness of the staff due to long-term absorption of dust;

[0015] 3. During use, the staff can start the electric push rod through the control panel. Since the fixed ring is fixed to the telescopic end of the electric push rod, and the fixed ring is fixed to the silo, the staff can adjust the height of the electric push rod, so that the staff can reach the top surface of the silo via a low escalator, which is convenient for the staff to pour raw materials into the silo from the feed port, thereby improving the safety of the device. During the loading process of the device, the staff can place the mold into the placement slot. Since the placement slot is directly above the feed pipe, the staff can adjust the height difference between the feed pipe and the mold through the control panel, so that the device can load molds of different heights, improving the applicability of the device.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 3As shown, an automatic loading device for a foam molding machine includes a silo 1. A drive motor 2 is fixed to the top surface of the silo 1. A rotating shaft 3 is provided at the output end of the drive motor 2. A plurality of stirring blades 4 are provided on the peripheral wall surface of the rotating shaft 3. The maximum distance between each two corresponding stirring blades 4 is similar to the diameter of the interior of the silo 1. A connecting rod 5 is fixed to the bottom surface of the rotating shaft 3. A spiral roller 6 is fixed to the bottom surface of the connecting rod 5. A buffer tube 7 is fixed to the bottom surface of the silo 1. The vertical cross-section of the buffer tube 7 is trapezoidal, and the diameter of its bottom gradually increases from bottom to top. The bottom surface of the buffer tube 7 is connected to a feed pipe 8. The maximum diameter of the spiral roller 6 is similar to the diameter of the interior of the feed pipe 8 and the same height. Two chutes 9 are provided on the inner wall surface of the silo 1. A drive slide 10 is provided inside the chutes 9. The top surface of the drive slide 10 is provided with a snap-in hole 11. The diameter of the two snap-in holes 11 when in contact is the same as the diameter of the connecting rod 5.

[0023] During use, the staff first starts the two driving slides 10 through the control panel 18, so that the two driving slides 10 contact each other. Since the diameter of the two clamping holes 11 after contact is the same as the diameter of the connecting rod 5, the bottom surface of the silo 1 is in a closed state. Then the staff pours the raw materials into the silo 1 through the feed port 22. At this time, the staff can start the driving motor 2 through the control panel 18. The rotation of the driving motor 2 drives the rotating shaft 3 to start rotating. During the rotation of the rotating shaft 3, several stirring blades 4 on the rotating shaft 3 begin to stir the raw materials in the silo 1. After a period of stirring, the staff can start the two driving slides 10 through the control panel 18, so that the two driving slides 10 separate. At this time, the stirred raw materials will fall into the buffer tube 7 under the action of gravity. Since the buffer tube 7 is connected to the feed pipe 8, the raw materials will enter the feed pipe 8. Since the vertical cross-section of the buffer tube 7 is trapezoidal, the diameter of its bottom gradually increases from bottom to top. In the process of the raw materials entering the feed pipe 8, the flow will be limited, thereby preventing too much raw material from falling at one time and forming a blockage. As the raw materials enter feed pipe 8, spiral roller 6, connected to shaft 3 via connecting rod 5, rotates with shaft 3. Since the maximum diameter of spiral roller 6 is similar to the internal diameter of feed pipe 8 and their height is the same, the raw materials, under the action of spiral roller 6, fall evenly from the bottom of feed pipe 8 into the mold. The connection between spiral roller 6 and shaft 3, as well as the slidable drive slide 10, ensures that the device not only fully agitates the raw materials but also uniformly discharges them, preventing any agglomeration and improving the stability of the device.

[0024] like Figures 1-4As shown, a vacuum cleaner 12 is fixed to the top surface of the silo 1. The suction end of the vacuum cleaner 12 is connected to the interior of the silo 1. A conduit 13 is provided at the other end of the vacuum cleaner 12. The other end of the conduit 13 is connected to a filter box 14. A filter plate 19 is provided inside the filter box 14. A vent 20 is provided at the rear end of the filter box 14. A feed port 22 is provided on the top surface of the silo 1. The inner wall of the feed port 22 is provided with a threaded groove 23. A twist cover 24 is provided inside the feed port 22. The twist cover 24 is threadedly connected to the threaded groove 23 on the inner wall of the feed port 22.

[0025] During use, after the staff pours the raw materials into the silo 1 through the feed port 22, they can thread the twist cover 24 into the threaded groove 23 on the inner wall of the feed port 22 to close the top surface of the silo 1. During the process of stirring and feeding the raw materials, the staff can start the vacuum cleaner 12 through the control panel 18. Since the suction end of the vacuum cleaner 12 is connected to the interior of the silo 1, the dust generated during the stirring and feeding process will be absorbed by the vacuum cleaner 12 and enter the filter box 14 through the conduit 13. Since the filter box 14 is provided with a filter plate 19 inside, the air will be filtered by the filter plate 19, thereby filtering the dust in the air in the filter plate 19, preventing the dust from flowing out of the feed pipe 8 to a certain extent, thereby preventing the staff from developing physical illnesses due to long-term dust absorption.

[0026] like Figure 1-Figure 2 As shown, a fixing ring 15 is fixed to the peripheral wall of the silo 1. An electric push rod 16 is fixed to the bottom surface of the fixing ring 15. A base 17 is fixed to the bottom surface of the electric push rod 16. A control panel 18 is provided on the top surface of the base 17. The drive motor 2, the drive slide 10, the vacuum cleaner 12, the electric push rod 16, and the control panel 18 are electrically connected. The base 17 is fixed to the filter box 14. A placement groove 21 is provided on the top surface of the base 17. The top surface of the placement groove 21 corresponds to the material conveying pipe 8.

[0027] During use, a worker can activate the electric push rod 16 via the control panel 18. Since the fixing ring 15 is fixed to the telescopic end of the electric push rod 16, and the fixing ring 15 is fixed to the silo 1, the worker can adjust the height of the electric push rod 16, allowing the worker to reach the top surface of the silo 1 via a low-height escalator, making it convenient for the worker to pour raw materials into the silo 1 from the feed port 22, thereby improving the safety of the device. During the loading process of the device, the worker can place the mold into the placement groove 21. Since the placement groove 21 is directly above the material delivery pipe 8, the worker can adjust the height difference between the material delivery pipe 8 and the mold via the control panel 18, so that the device can load molds of different heights, improving the applicability of the device.

[0028] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
